Lowrance HDS-12 Gen2 Touch Sonar/GPS Combo with 50/200 kHz Transducer - $1,949.88

The improved 12 touch-screen display features easier-to-use menus and five push-button controls. These modifications simplify the sonar/GPS operation without sacrificing features. Thanks to its 1,500-nit brightness rating, the wide-angle SolarMAX display delivers superior sunlight viewing. Four-channel sonar technology combines the award-winning Broadband Sounder with the Left-, Right- and DownScan viewing of StructureScan. The DownScan Overlay combines the Broadband Sounder and DownScan imaging together onto one screen. The TrackBack feature lets you scroll back through the sonars history, so you can mark waypoints that you want to return to. Works with both the Broadband Sounder and StructureScan. Dual-Chart viewing displays Navionics and Insight Mapping simultaneously, giving you the best of both navigational views. The StructureMap Overlay uses StructureScan left- and right-side images on any map for an easy-to-interpret picture of the structures below, and where they are in relation to your boat. The Insight Genesis lets you create your own map. Made from your recorded sonar data, these high-resolution and perfectly accurate maps display 1-ft. contours, bottom hardness and weedlines. Compatible with Broadband 3G and 4G radar, Sirius Satellite radio and weather receiver, LGC-4000 external GPS antenna and SonicHub stereo system. Includes Ethernet port and two SD-card slots. Two-year warranty. - $1,949.88
